Many writers have suggested that professionals dealing with psychological problems in school settings need to consider procedures for consulting on a system level, rather than on an individual or a group level. In this report, a token eccnomy system was implemented for all 459 students in a K-6 elementary school. Managing an intervention program at the system level required comprehensive procedures for staff training and program modification. The results showed a major decrease in classroom disruptions and a decrease in negative teacher interactions during the token economy system compared with baseline data. Data analysis the following summer on system-wide variables demonstrated that the number of suspended students and number of days of suspension decreased, that the rate of gain on achievement tests in reading and mathematics inrreased compared with the yearly rates suggested by test scores the previous year, and that the teacher turnover rate decreased. Several variables considered necessary for the effective implementation of the program were discussed.The need exists for the psychologist in the schools to go beyond individual child or group problem-solving to the level of system intervention. In the consultative model for school psychological services described by Meyers (1973), the fourth and highest level of consultation focuses not on change in children and individual teachers, but rather on changing the behavior of groups within the system, such as groups of teachers or administrators or both. These individuals would then be responsible for changes in the children's behavior. Bardon and Bennett (1967) have been early advocates of a system-wide consultant model for the school psychologist. The need for university training programs to provide training a t the systems level also has been emphasized (Bardon & Bennett, 1967;Reilly & Pryzwansky, 1973).The necessity for considering system procedures to enhance the effectiveness of behavior modification in the school setting recently has been articulated by Nelson, who described four areas of expansion: "the interaction between social and academic behaviors, the manipulation of antecedent conditions to help produce reinforceable responses, the use of school-system-wide variables to modify behavior, and the inclusion of standardized tests as dependent variables" (Nelson, 1974, p. 176).It was the purpose of this study to implement a token economy system across an entire school and to assess the effects of such systemwide intervention. To do so it was necessary to arrange procedures for training the principal, teachers, and staff in the basic principles of behavior modification and in procedures of the token economy system, to reach agreement on goals and objectives, and to obtain consistency in program implementation. The following is an account of how these procedures were arranged in an elementary school for over 450 children.Requests for reprints should be sent to R.
